Description
Technical field
The utility model is related to a kind of steel fireproof double-opening door.Belong to double door technical field.
Background technology
It is well known that fire resistant doorsets are widely applied in all kinds of buildings, according to the existing standard GB/T 12955 of China-
2008《Fire resistant doorsets》Regulation, fire resistant doorsets are divided into four major classes：It is fire resistance steel door, fire-proof wooden door, the wooden fire prevention of steel respectively
Door and other material fireproof doors, wherein fire resistance steel door are to make doorframe, door leaf skeleton and door skin with steel material, wooden
Fire resistant doorsets are to make doorframe, door leaf skeleton and door skin with fire retardant timber or fire retardant timber-work, and steel fire-proof wooden door is
Doorframe, door leaf skeleton and door skin, other materials fire prevention are made with steel and fire retardant wood materials or fire retardant timber-work
Door is using steel, difficulty with the inorganic incombustible material in addition to steel, fire retardant wood materials or fire retardant timber-work or part
Firebrand material or fire retardant timber-work make doorframe, door leaf skeleton and door skin.At present, fire resistance steel door and wooden anti-
Vent is widely used by the market, is analyzed from the fire resistance and performance attractive in appearance of fire resistant doorsets, the fire integrity of fire resistance steel door,
Stability is best, but outward appearance facing is dull, and aesthetic property is poor, and fire-proof wooden door is due to material itself, and intensity is weaker, plus
Fire-retarding of wood processing complex process, it is careless slightly, the flame retardant effect of timber will be had a strong impact on, although therefore occurring in that
The surface of timber is easily decorated, and aesthetic property is good, but fire stability is relatively poor, and raw material processing cost is higher, service life
Shorter phenomenon.
Existing fire resistance steel door is to be filled in steel metal material as reinforcement inside door leaf, so steel is prevented fires
Door meet fire when can be deformed because of high temperature, cause thoroughly fiery at deformation, in addition, metal reinforcing at high temperature intensity by there is change
To nothing, so that do not reach resistance to deformation and fireproof effect, and also producing efficiency is relatively low, while the waste of material can be caused, it is existing
Double door fan deformation at for angle on leaf lock side, easy fire thoroughly here.Existing most of steel door leaf using surrounding and
Middle part reinforcement, so not only weight is big, efficiency is low, cost is high, and last fire integrity effect is simultaneously unstable.
Utility model content
Good the utility model proposes a kind of fire insulation, door core is firm, is unlikely to deform, and the longer steel of service life is prevented
Fiery double door, solves the problem of prior art is present.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of steel fireproof double-opening door, including doorframe and door leaf；The doorframe includes the first door frame and the second door frame,
The door leaf is arranged on first door frame and the second door frame by the hinge of more than 2, first door frame and
Second door frame is connected with each other by the first reinforcing frame and the second reinforcing frame, the outside of first reinforcing frame and the second reinforcing frame
Fire-proof plate and Fireproof cover shrouding are provided with, the door leaf includes Midst density flame retardant fibre board, fireproof core board group successively from the inside to the outside
It is provided with part and Midst density flame retardant fibre board, the fireproof core board component between multiple X-shaped supports, the adjacent X-shaped support
Filled with glass magnesium core plate, the doorframe is made up of cold-rolling galvanization steel plate.
The doorframe is additionally provided with pick-proof nail.
The material of the X-shaped support is stainless steel.
The doorframe outer surface is cast with fireproofing inorganic binder materials coating.
The X-shaped support in the closing space of Midst density flame retardant fibre board formation with being filled with perlite particle.Phase
The adjacent perlite particle is spliced by inorganic refractory mud.
The characteristics of the utility model has following and beneficial effect：
A kind of steel fireproof double-opening door that the utility model is related to is by setting by Midst density flame retardant fibre board, fireproof core board
The multiple X-shaped supports set in the door leaf and fireproof core board component of component and Midst density flame retardant fibre board composition, fireproof core board group
Using the skeleton of steel inside the fire proofing material of filling in part, whole double door, the complete of double door fire resistance is improved well
Whole property and stability, surface use wood materials, while the dicoration of double door outward appearance is improved, by changing structure and material
It is compound, be further ensured that the premise of fire-proof door leaf fire protecting performance, while improve the dicoration of fire-proof door leaf, reach more fire resisting and
Double effectses more attractive in appearance.
